RAILWAY-RAIL-JOINT FASTENING.

Specification of Letters Patent.

Patented Sept. 21, 1909.

Application filed. November 20, 1908. Serial No. 463,679.

To all whom 'it may concern:

Be it known that we, CHARLES DREIBUSS and ANTHONY F. KULAGE, citizens ofthe United States, residing at St. Louis, State of Missouri, haveinvented a new and useful Railway-Rail'Joint Fastening.

Our invention relates to improvements in railway-rail joint fastenings,in which the railway rails are fastened by means of perforated fishplates held together by half round wedge shaped keys, which keys aretightened by driving them together and toward each other, and which areheld tight by means of small teeth and notches in their surfaces, whichteeth and notches grip the outside edge of the fish plate and a tongueon the head of the key.

The object of our invention is first :to substitute for the usual boltsnow used in railway rail joint fastenings half round taperedwedge-shaped keys with teeth on one side and notches on the other side.Second :to provide a key bolt that will fit any perforated fish plate,be the perforation round, elliptical or well worn. Third :to provide akey bolt that can be tightened at any time that the perforation in thefish plate becomes larger by wear, contraction, or jar of cars passingover the rails.

The objects are attained by means illustrated in the accompanyingdrawings in which Figure l is a vertical section of the railway railsand fish plates together with a side view of two keys driven tight,showing how the teeth on the surface of the key grasp the outside edgeof the fish plate and how the tongue on the head of the key grasps thenotches on the inside surface of the key; Fig. 2 is a fullsize top Viewof the key; and Fig. 3 is a full size side view of the ke Similarletters refer to similar parts throughout the several views.

Referring to Fig. 1 the railway rails are represented by the letter A;the fish plates which join the rails are represented by letter B. LetterC. represents the key as a whole; letter D. the half round tapered shankof the key G, the square head of the key C. is shown by E. Letter F.shows a series of notches in the fiat and inside surface of the shank ofthe key (3., into which notches F. a tongue G. on the head E. of the keyfits, and holds fast the other key which goes to make up the bolt. Oneof the teeth H, on the rounded surface of shank D.

grasps the outside edge of the hole in the fish plate, and the tongue G.catches in one of the notches F. Letter I indicates the pointed end ofthe shank D. The shank D. is pointed, which is shown by the letter I sothat the point of the key C. will follow the fiat rounded inside surfaceat J.

In Fig. 9. a top view of the key C. is shown with the teeth H near theend of the shank D. The tongue which grasps the notches F. on the insideof the other key is shown by G. A tapered rib L. extends from the headE. half way the length of the shank D. which rib L. makes it possiblefor the key to fit any sized hole or any well worn hole in the fishplate. The burs K. are projections on the shank D. which will permit thekey to be used either in a round or elliptical hole in the fish plate.

Referring to Fig. 3, the notches into which the tongue G. fits are shownin dotted lines in the fiat surface M. by the letter F. The semicircularsurface of the shank D. is shown by letter N. The teeth which grasp theedge of the hole in the fish plate B. are shown by the letter H.

In fastening the fish plates joining the rails the keys are placed intothe holes, one on each side and driven toward each other. As this isdone the points I slide along the flat rounded surface J. and the teethH grasp the edge of the hole in the fish plate and at the same time thetongue G. slips into one of the notches F. If the holes in the fishplates are elliptical or worn instead of the standard size, the burs K.will fill in the elliptical part of the hole and if the fish plate holeis too large besides elliptical, because of wear, the rib L. will fillin this part.

\Ve are aware that key bolts of this nature have been invented but ourimprovements consist in the burs K. and the rib L. which permit the boltto be used for any sized hole; and the teeth and notches on the surfacesof the shank D. which fasten the fish plates tightly when the keys havebeen driven home.

What we claim as new and desire to secure by Letters Patent is 1. Thecombination, with the railway rails A and fish plates B B, of the keybolts C C having a series of teeth on the rounded surfaces of theirshanks, and having a series of beveled notches in the fiat surfaces oftheir shanks, and having projecting tongues on the edge of the heads ofthe key bolts C C which tongues fit into the beveled notches I of thecorresponding key bolts applied to said rails and fish plates,substantially as shown and described.

2. The combination, with the railway rails A and fish plates 13 B, ofthe key bolts C C having a tapered rib L on the rounded surface of theirshank and burs K K on the sides of their shank, and having a series ofteeth on the rounded surface of their shanks and a series of bevelednotches in the fiat surface of their shanks and having a projectingtongue on the edge of the head of the key bolts C C, which tongue fitsinto the beveled notches of the corresponding key bolt, applied to saidrails and fish plates, substan tially as shown and described.
